Answer:
C (0.9)
Step-by-step explanation:
Key skills needed: Solving one variable equations
1) we have the equation --> 12.72 = 5.52 + 8x
2) We need to solve for x.
To get x by itself, we subtract 5.52 from both sides. (12.72 - 5.52 = 7.2)
This means 8x = 7.2
3) Divide by 8 from both sides, and you will get x = 0.9 (7.2/8 = 0.9)

HOPE IT HELPS YOU!!!someone knows it, I need help
Answer:
The answer is A.
Step-by-step explanation:
In order to simplify, you have to collect like terms :
x² - 3xy - 5xy - 7y² + 4x² + 8y²
= (x² + 4x²) + (-3xy - 5xy) + (-7y² + 8y²)
= 5x² - 8xy + y²
Step by step explanation
Answer:
[tex]\huge\boxed{\tt{x = -5 , y = 2}}[/tex]
Step-by-step explanation:
x = y - 7 ---------------------(1)
-y - 2x = 8 --------------------(2)
Put Equation (1) into (2)
- y - 2 ( y-7 ) = 8
-y - 2y + 14 = 8
-3y = 8 - 14
-3y = -6
Divide -3 to both sides
y = -6 / -3
y = 2
Put y = 2 in (1)
x = 2 - 7
x = -5
So,
x = -5 , y = 2

~AH18072. Given the graph below, answer the following questions.
У
a. What is the function that represents line A?
this is for a retake for geometry pls help
Answer:
B. 40, 51.5, 88.5
Step-by-step explanation:
(5x - 4) + (2x + 3) + (3x- 4) = 180
10x - 5 = 180
10x = 185
x= 18.5
Substitute
5(18.5) - 4 = 88.5
2(18.5) + 3 = 40
3(18.5) - 4 = 51.5

A printer is printing photos. For every 15 photos, the printer takes 3 minutes.
Complete the table below showing the number of photos and the time it takes to print them.
Answer:
20, 6, 45, 10
Step-by-step explanation:
each minute is 5 papers so 3 min is 15 then 4 min is 20 papers
Answer: Number of photos: 15,25,35,40,50
Time: 3,5,7,8,10
Step-by-step explanation:
To find the time we divide the number of photos by 5. To find the number of photos we multiply the time by 5.when the number of photos is 35, the time is 35 divided by 5 which equals 7 minutes.

Solve the inequality and enter your solution as an inequality comparing variable to solution-31>x-48
Answer:
solving the inequality [tex]-31>x-48[/tex] we get: [tex]\mathbf{x<17}[/tex]
Step-by-step explanation:
We need to solve the inequality [tex]-31>x-48[/tex]
Solving the inequality and finding value of x:
[tex]-31>x-48[/tex]
First we will be switching sides i.e. left hand side will become right hand side and right hand side will become left hand side. In doing so, the inequality sign i.e. > will be reversed and changed with <
[tex]x-48<-31[/tex]
Now, for finding value of x, we will be adding 48 on both sides
[tex]x-48+48<-31+48\\x<17[/tex]
The value of x is less than 17 i.e. [tex]\mathbf{x<17}[/tex]
So, solving the inequality [tex]-31>x-48[/tex] we get: [tex]\mathbf{x<17}[/tex]

The length of which line segment is equal to the exact value of the sine if theta?
Option 3: line segment OR
Option 4: line segment OS
====================================================
Explanation:
Recall that the sine of an angle is equal to the ratio of opposite over hypotenuse.
In other words,
sin(angle) = opposite/hypotenuse
With respect to reference angle theta, the side TS is opposite this angle. It is the leg furthest from the angle. The hypotenuse is the longest side segment TO. The hypotenuse is always opposite the 90 degree angle.
For a unit circle, the radius is 1, so segment TO is 1 unit long.
Therefore,
sin(angle) = opposite/hypotenuse
sin(theta) = TS/TO
sin(theta) = TS/1
sin(theta) = TS
The vertex of a quadratic function is (6, 2), and the y-intercept of the function is (0, −70). The equation of the function in vertex form, f(x)=a(x−h)2+k, is shown.−70=a(0−6) squared+2
Answer:
The equation of the function in vertex form is represented by [tex]y = -2\cdot (x-6)^{2}+2[/tex].
Step-by-step explanation:
Let [tex](h,k) = (6,2)[/tex] and [tex](x,y) = (0, - 70)[/tex], now we substitute on the equation of the quadratic function and solve for [tex]a[/tex]:
[tex]y = a\cdot (x-h)^{2}+k[/tex]
[tex]-70 = a\cdot (0-6)^{2}+2[/tex]
[tex]-70 = 36\cdot a + 2[/tex]
[tex]36\cdot a = -72[/tex]
[tex]a = -2[/tex]
Therefore, the equation of the function in vertex form is represented by [tex]y = -2\cdot (x-6)^{2}+2[/tex].
